They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts.
it will enter from air
Virus cannot replicate themselves. They should enter a living cell
Some viruses are very specific to certain cells. The cell has proteins on it's surface and a virus will use it a docking station to be able to enter the cell. Some cells don't have that protein and the virus can not enter the cell.
enter cell, attach to cell, replicate, kill cell
The capsid of a virus is surrounded by an envelope, which is derived from the host cell membrane during the viral replication process. This envelope contains viral glycoproteins that help the virus attach to and enter into host cells.
multiply
A virus attaches to a host cell by recognizing and binding to specific proteins or receptors on the cell surface. This attachment is necessary for the virus to enter the host cell and begin the process of infection.
A virus attaches to a specific cell because it has proteins on its surface that can only bind to receptors on that specific cell. This binding is necessary for the virus to enter the cell and replicate. This specificity is determined by the structure of the virus and the receptors on the cell surface.
True. The envelope of a virus helps it enter the host cell by fusing with the cell membrane. The virus DNA can be found enclosed within this envelope, along with other viral proteins necessary for infection and replication.
The specific viral proteins on the surface of the virus determine its attachment to host cell membrane receptors. These proteins bind to complementary host cell receptors, allowing the virus to attach and enter the host cell.
computer propagation tricks
The virus slams against the nerve cell and opens the nerve cell's membrane by fusing its membrane with it. The contents of the virus enter the nerves and begin the negative effects.
